Mint18 Sony Vaio

[kszan]

Hi all,
I am new here.
I installed Mint 18 on an old Sony Vaio VGN-FE770G. The OS is working great on the laptop but I cannot seem to use the internal wifi card. I bought a TP-Link TL-WN725N and plugged it in.
I followed instructions on this forum from several posts but I can't seem to get anywhere.
The Ethernet is working great, when I turn on WIFI it says it is working yet no wireless networks are detected.

I would appreciate help to resolve this issue.

Does the Vaio have a slider switch on the front edge? If not you may have to remove the internal card to see if it will allow the USB to function

What version is the wifi chipset inside the TLWN725N? It should be listed on the label on the adapter. V1, V2, or V3?

TP-Link TLWN275N 150MBs WiFi Nano USB Adapter
V1: Realtek RTL8188CUS
V2: Realtek RTL8188EUS
V3: Realtek RTL8188EUS

Post the output for: (with the TLWN725N plugged in)

Thank you, that solved it. I feel pretty stupid right about now lol.
The slider switch was off.

My Vaio has a wifi on/off switch on the front left edge which I bump now and then.
Glad it's working.

Now I am getting "activating failed error, active connection removed before it was initialized"

I would try a reboot and attempt to connect

Everytime I restart I have to sudo service NetworkManager start and I am still getting the same error from the wifi "activating failed error, active connection removed before it was initialized"
